If you or someone you know has some basic mechanical knowledge it's a pretty easy job. Euro car parts will probably charge you about £50 for a recon. there will be a surcharge as you will have to take the old one back
You should be able to get an exchange recon motor for around £70, as for fitting yourself, depending on experience and work space it isn't too much of a job. Saying that, it might be worth geting some prices from a garage and supply the part yourself if it's easier on you?
